This year marks the 100th anniversary of mathematician and logician Alan Turing's birth. I had the honor to discuss his legacy with some of the most influential computer scientists in the world at the Association for Computing Machinery's 2012Turing Award celebration.

 

In Part 1 of a two-part series, listen as Frances Allen, Charles Bachman, Vint Cerf, Dame Wendy Hall, William Newman, Christos Papadimitriou and Judea Pearl celebrate the mind of Alan Turing, the father of computer science.

 

WENDY HALL: He was a prodigy. I mean, he got his degree very early, became a fellow at King's College, Cambridge very early, and had a remarkable brain. And the insight, you know, he's a true--I think--a true genius.

CHRISTOS PAPADIMITRIOU: I think that Turing is one of the greatest persons who ever lived, and I don't mean scientists.

 

FRANCES ALLEN: He was one of the most insightful and brilliant people.

 

CHARLES BACHMAN: He made tremendous contributions to the British war effort, and also, indirectly to the American war effort.

 

JUDEA PEARL: ... he understood the call of the hour.

 

CP: In human history, I think there are very few good guys who affected history more dramatically than Alan Turing.

 

VINT CERF: I think the most important thing about Turing, though, is to recognize the incredible breadth of his thinking and the depth of his ability to start from first principles to reason his way to some conclusion.

 

WH: Well, I think he's somebody that was just a brilliant brain, and could help define new fields in whichever area he went into.

 

CB: As a very young child he was very precocious in some of the things he did mathematically and designing experiments, but he was not a very social young boy.

 

FA: Probably a loner.

 

WH: But by all accounts he was quite a difficult person, like a lot of geeks are, you know.

 

FA: Pretty widely acknowledged that he gave his mother a very hard time. You know, he was not an easy person.

 

WH: But there's plenty of people who would call him a friend and he obviously had a rich social life.

 

CB: Some children kind of do things by themselves and others do things in groups. He was kind of a solitary child in the early years and only developed later, through his activities, some social skills.

 

VC: My favorite story is the one where a young man who knew him as a boy was describing that he was awakened one morning by somebody pounding on the door, and when he opened the door it's Alan Turing, who, by the way, was well known for running. I mean, he was a distance runner.

 

CB: In a time when he was working at Bletchley Park, which was about 40 miles from London, and he had a business meeting at the National Physical Laboratory in London, he would run to town for the meeting and he would run back.

 

VC: So dressed in his running shorts, he's holding a leaf from a Rhododendron, and he didn't have any paper and he wanted to leave them with an invitation to come to a party. And so he was writing on the Rhododendron leaf. And I thought, 'there's nothing more wonderful about that story than the ability of Alan Turing to take advantage of anything, you know, that would come to hand in order to do what he was doing.'

 

CP: By all accounts, he was probably a very central figure in the brilliant cryptanalytic effort of the British counterintelligence.

 

CB: His best-known contributions are those he handled working on the British Intelligence Service during World War II, when they built the machines to help decode the German Enigma code.

 

VC: The machine that Turing designed actually emulated the way the Enigmas worked. They used four rotors that would turn in various ways depending on what was typed on a typewriter.

 

CP: By creating his special-purpose computers so that they broke German codes, apparently he played a major role in the Battle of the Atlantic.

 

CB: And that part of his work is very practical. He took his theory and turned it into things.

 

VC: So what they would do is build this giant machine that pretended like it was literally many, many of these encryptors, in order to set them all at slightly different positions in the keying space, in order to see whether one of them would break the code and translate it.

 

WH: It can be argued that the team at Bletchley Park saved on the order of 20 million lives, because they managed to stop the U-boats, and it really quickened the end of the war.

 

WILLIAM NEWMAN: His work made a huge difference to the outcome of the war and certainly to the duration of the war.

 

JP: Many people attribute to him shortening the war by six months. I think it was more than that.

 

VC: So his design was extremely practical and, at the time, one of the most interesting examples of parallel computing that you would find.

 

JP: It's really amazing.

The Case for Reparations

 

Two hundred fifty years of slavery. Ninety years of Jim Crow. Sixty years of separate but equal. Thirty-five years of racist housing policy. Until we reckon with our compounding moral debts, America will never be whole.

A Look At 19th Century Children In The USA

PHILADELPHIA — DINNER with your children in 19th-century America often required some self-control. Berry stains in your daughter’s hair? Good for her. Raccoon bites running up your boy’s arms? Bet he had an interesting day.

 

As this year’s summer vacation begins, many parents contemplate how to rein in their kids. But there was a time when Americans pushed in the opposite direction, preserved in Mark Twain’s cat-swinging scamps. Parents back then encouraged kids to get some wildness out of their system, to express the republic’s revolutionary values.

A late 19th century family taking a stroll down a set of railroad tracks

American children of the 19th century had a reputation. Returning British visitors reported on American kids who showed no respect, who swore and fought, who appeared — at age 10 — “calling for liquor at the bar, or puffing a cigar in the streets,” as one wrote. There were really no children in 19th-century America, travelers often claimed, only “small stuck-up caricatures of men and women.”

 

This was not a “carefree” nation, too rough-hewed to teach proper manners; adults deliberately chose to express new values by raising “go-ahead” boys and girls. The result mixed democracy and mob rule, assertiveness and cruelty, sudden freedom and strict boundaries. Visitors noted how American fathers would brag that their disobedient children were actually “young republicans,” liberated from old hierarchies. Children were still expected to be deferential to elders, but many were trained to embody their nation’s revolutionary virtues. “The theory of the equality” was present at the ballot box, according to one sympathetic Englishman, but “rampant in the nursery.”

 

Boys, in particular, spent their childhoods in a rowdy outdoor subculture. After age 5 or so they needed little attention from their mothers, but were not big enough to help their fathers work. So until age 10 or 12 they spent much of their time playing or fighting.

 

The writer William Dean Howells recalled his ordinary, violent Ohio childhood, immersed in his loose gang of pals, rarely catching a “glimpse of life much higher than the middle of a man.” Howells’s peers were “always stoning something,” whether friends, rivals or stray dogs. They left a trail of maimed animals behind them, often hurt in sloppy attempts to domesticate wild pets.

 

And though we envision innocents playing with a hoop and a stick, many preferred “mumbletypeg” — a game where two players competed to see who could throw a knife closer to his own foot. Stabbing yourself meant a win by default.

 

Left to their own devices, boys learned an assertive style that shaped their futures. The story of every 19th-century empire builder — Carnegie, Rockefeller, Vanderbilt — seems to begin with a striving 10-year-old. “Boy culture” offered training for the challenges of American manhood and a reprieve before a life of labor.

 

But these unsupervised boys also formed gangs that harassed the mentally ill, the handicapped and racial and ethnic minorities. Boys played an outsize role in the anti-Irish pogroms in 1840s Philadelphia, the brutal New York City draft riots targeting African-Americans during the Civil War and attacks on Chinese laborers in Gilded Age California. These children did not invent the bigotry rampant in white America, but their unrestrained upbringing let them enact what their parents mostly muttered.

 

Their sisters followed a different path. Girls were usually assigned more of their mothers’ tasks. An 8-year-old girl would be expected to help with the wash or other physically demanding tasks, while her brother might simply be too small, too slow or too annoying to drive the plow with his father. But despite their drudgery, 19th-century American girls still found time for tree climbing, bonfire building and waterfall-jumping antics. There were few pretty pink princesses in 19th-century America: Girls were too rowdy and too republican for that.

 

So how did we get from “democratic sucklings” to helicopter parents? Though many point to a rise of parental worrying after the 1970s, this was an incremental change in a movement that began a hundred years earlier.

 

In the last quarter of the 19th century, middle-class parents launched a self-conscious project to protect children. Urban professionals began to focus on children’s vulnerabilities. Well-to-do worriers no longer needed to raise tough dairymaids or cunning newsboys; the changing economy demanded careful managers of businesses or households, and restrained company men, capable of navigating big institutions.

 

Demographics played a role as well: By 1900 American women had half as many children as they did in 1800, and those children were twice as likely to live through infancy as they were in 1850. Ironically, as their children faced fewer dangers, parents worried more about their protection.

 

Instead of seeing boys and girls as capable, clever, knockabout scamps, many reconceived children as vulnerable, weak and naïve. Reformers introduced child labor laws, divided kids by age in school and monitored their play. Jane Addams particularly worked to fit children into the new industrial order, condemning “this stupid experiment of organizing work and failing to organize play.”

 

There was good reason to tame the boys and girls of the 19th century, if only for stray cats’ sake. But somewhere between Jane Addams and Nancy Grace, Americans lost track of their larger goal. Earlier parents raised their kids to express values their society trumpeted.

 

“Precocious” 19th-century troublemakers asserted their parents’ democratic beliefs and fit into an economy that had little use for 8-year-olds but idealized striving, self-made men. Reformers designed their Boy Scouts to meet the demands of the 20th century, teaching organization and rebalancing the relationship between play and work. Both movements agreed, in their didactic ways, that playtime shaped future citizens.

 

Does the overprotected child articulate values we are proud of in 2014? Nothing is easier than judging other peoples’ parenting, but there is a side of contemporary American culture — fearful, litigious, controlling — that we do not brag about but that we reveal in our child rearing, and that runs contrary to our self-image as an open, optimistic nation. Maybe this is why sheltering parents come in for so much easy criticism: A visit to the playground exposes traits we would rather not recognize.

 

There is, however, a saving grace that parents will notice this summer. Kids are harder to guide and shape, as William Dean Howells put it, “than grown people are apt to think.” It is as true today as it was two centuries ago: “Everywhere and always the world of boys is outside of the laws that govern grown-up communities.” Somehow, they’ll manage to go their own way.

Investigating Family's Wealth, China's Leader Signals a Change

From The New York Times 

By CHRISTOPHER DREW and JAD MOUAWAD

APRIL 19, 2014

 

HONG KONG — His son landed contracts to sell equipment to state oil fields and thousands of filling stations across China. His son’s mother-in-law held stakes in pipelines and natural gas pumps from Sichuan Province in the west to the southern isle of Hainan. And his sister-in-law, working from one of Beijing’s most prestigious office buildings, invested in mines, property and energy projects.

 

In thousands of pages of corporate documents describing these ventures, the name that never appears is his own: Zhou Yongkang, the formidable Chinese Communist Party leader who served as China’s top security official and the de facto boss of its oil industry.

But President Xi Jinping has targeted Mr. Zhou in an extraordinary corruption inquiry, a first for a Chinese party leader of Mr. Zhou’s rank, and put his family’s extensive business interests in the cross hairs.

 

Even by the cutthroat standards of Chinese politics, it is a bold maneuver. The finances of the families of senior leaders are among the deepest and most politically delicate secrets in China. The party has for years followed a tacit rule that relatives of the elite could prosper from the country’s economic opening, which rewarded loyalty and helped avert rifts in the leadership.
